    Abstract: A conical radiator coupled to an antenna patch disposed along a first end of the radiator, said patch disposed on an insulator. A ground plane is connected to the insulator and a radome is disposed opposite a second end of the radiator. The radome has a first region presenting a convex surface towards the radiator, and a second region presenting a concave surface towards the radiator. The first end of the conical radiator is the apex of the cone. A ground plane is included and a portion of the ground plane is a planar surface and another portion extends away from the planar portion towards the radome. Also disclosed is a method for forming a radiation pattern by shaping the radome to effectuate a predetermined radiation pattern using localized convex and concave surfaces positioned on the radome at different points in relation to the conical radiator.

  • Publication number: 20150042513
    Abstract: Broadband slot-coupled stacked patch antenna elements are capable of continuous broadband operation between 1.71 GHz and 2.69 GHz. The broadband slot-coupled stacked patch antenna element includes a mid-band radiating patch, a high-band radiating patch, and a low-band resonator with coupling slots capable of resonating at low, mid, and high band frequencies. Additionally, a low-profile probe-fed patch element is provided for pattern enhancement of antenna arrays at high-band frequencies. This low-profile patch element features fan-shaped probes that have three degrees of tune-ability, namely a length, a width, and a spreading angle. Further aspects include 3-column and 4-column offset arrays of the broadband patch radiators and an interleaved array of the low-profile high-band patch radiators and the broadband radiating elements. A new type of azimuth beam forming network (ABFN) is also introduced for the beam forming of the 3-column and 4-column dual-beam arrays.

  • Patent number: 8914258
    Abstract: An RF feed element for an antenna system required to comply with a set of specified secondary pattern characteristics is designed by performing a quantitative optimization of the RF feed element directly with respect to the secondary pattern characteristics. The quantitative optimization may include pre-computing a plurality of partial secondary pattern complex field values. Each partial secondary pattern may be associated with an RF feed element modal beamlet. A value of at least one to-be-optimized feature is optimized by iteratively adjusting the value of the to-be-optimized feature(s) within an optimization loop that iteratively computes secondary pattern characteristics and compares them to the specified secondary pattern characteristics.
